History

Daeron loved Lúthien, daughter of Thingol and Melian the Maia, but she did not love him. Nevertheless they were good friends, and Lúthien would often dance to his music. After Daeron found out about Lúthien's love for the mortal Beren, he betrayed them both to Thingol. When Lúthien later sought his help in assisting captive Beren, Daeron again betrayed her to Thingol, though this time in love and fear for her rather than jealousy.

After Lúthien departed in secret from Doriath, Daeron repented and set out to search for her. He never did find her and never returned to Doriath either, passing over the Ered Luin into the East where he apparently dwelt long after.[5]

Other Versions of the Legendarium

In earlier versions of the mythology as set out in The History of Middle-earth, Daeron was originally envisioned as Lúthien's brother.[9] Daeron's name went through a number of changes before Tolkien settled upon the final form - first it was Kapalen, then Tifanto, then Dairon, before Daeron.[10]
